Reviews of Silkolene 5/40 synthetic oil (1 litre)

Great oil? Iain Davis on Sep 08, 2026

Rating: 5

NN asked me for a review. I only bought oil so all I can say is that it was definitely brown and runny (but not too runny) and I'm relatively confident that it is doing a great job or lubricating all the right parts of my bike. If at any point I discover that it has failed to lubricate anything I will certainly be amending my review but, as of now, all seems to be going well!

Handy 1 litre top up size, only needed half a litre so carry the other around in my panniers for emergency use. Have to say shifting was so much smoother after adding 0.5 litres top up, previously used whatever OEM oil my BMW dealer used, might now change to this
